The device includes a press roller and a first moving device. The press roller includes a peripheral portion. The peripheral portion of the press roller depresses the straight parts of the fiber bundle engaged with the pins toward the roots of the pins in the vicinity of the pin. The first moving device moves the press roller in the arrangement direction of the pins such that the peripheral portion sequentially intersects the straight parts of the fiber bundle. The peripheral portion is located in the front of the press roller in the moving direction, and the press roller is moved to sequentially intersect the straight parts of the fiber bundle while being inclined such that, toward the front end in the moving direction of the press roller, the distance from the roots of the pins in the laminating direction of the fiber bundle layers increases.
Description
- The present invention relates to a fiber bundle arranging device and a fiber bundle arranging method that arrange a fiber bundle by drawing out the fiber bundle from a guide hole of a guide pipe by moving the guide pipe with the fiber bundle being engaged with arranged pins.
- Conventionally, composites that use three-dimensional fabric (three-dimensional fiber structure) as reinforcing material have been proposed as fiber-reinforced composites, which are widely used as light structural material. The fiber-reinforced composites have extremely high strength, and are used as part of structural material of, for example, aircraft. As a method for producing the three-dimensional fiber structure used in the reinforcing material of the fiber-reinforced composites, a method has been proposed in which a fiber bundle lamination is formed by laminating fiber bundle layers, each of which is formed by folding back a fiber bundle, to be at least biaxially oriented, and the fiber bundle lamination is connected by a thickness direction thread arranged perpendicular to the fiber bundle layers.
Patent Documents 1 and 2 each disclose a fiber bundle arranging device that forms fiber bundle layers by feeding a fiber bundle from a guide pipe, which moves along an arranging surface, and arranging the fiber bundle to be folded back and forth between pins arranged at a predetermined pitch in a state where the fiber bundle is flat and the flat surface of the fiber bundle is arranged along the arranging surface. - From the aspect of the physical property of the three-dimensional fiber structure, the fiber density of the fiber bundle is preferably high. To increase the fiber density of the fiber bundle, fiber bundle array engaged with the pins may be depressed toward the roots of the pins in the vicinity of the pins. For example, depression means including a press plate and a pair of press blocks as disclosed in
Patent Document 1 has been proposed as a depressing mechanism. The press plate and the pair of press blocks have lengths substantially equal to the length of the array of pins arranged in one direction. The press plate and the pair of press blocks press the fiber bundle at once along the entire length of the array of pins. - However, since the depression means disclosed in
Patent Document 1 has the length substantially equal to the length of the array of pins, the fiber bundle arranging device is disadvantageously large. - Furthermore, the depression means disclosed in
Patent Document 1 is not placed at the position where pressing operation should be performed while the fiber bundle is being arranged. Thus, the depression means needs to be placed at the position where pressing operation should be performed after arranging the fiber bundle corresponding to one layer of the fiber bundle layers. With this procedure, however, time is taken to form the fiber bundle layers including the pressing operation. - Patent Document 1: Japanese Laid-Open Patent Publication No.

2007-16347 - A first objective of the present invention is to reduce the size of a fiber bundle arranging device. A second objective of the present invention is to permit a fiber bundle to be pressed while arranging the fiber bundle during at least part of the period of arranging the fiber bundle of one fiber bundle layer.
- To achieve the above objective, a first aspect of the present invention provides a fiber bundle arranging device for laminating fiber bundle layers formed of a fiber bundle. The fiber bundle is engaged with arranged pins to have straight parts. The device includes a pressing member and a first moving device. The pressing member includes a pressing portion. The pressing portion depresses the straight parts of the fiber bundle engaged with the pins toward the roots of the pins in the vicinity of the pins. The first moving device moves the pressing member in the arrangement direction of the pins such that the pressing portion sequentially intersects the straight parts of the fiber bundle. The pressing portion is located in the front of the pressing member in the moving direction, and the pressing portion is moved to sequentially intersect the straight parts of the fiber bundle while being inclined such that, toward the end in the moving direction, the distance from the roots of the pins in the laminating direction of the fiber bundle layers increases.
- A second aspect of the present invention provides a fiber bundle arranging method for laminating fiber bundle layers formed of a fiber bundle. The fiber bundle is engaged with arranged pins to have straight parts. The method includes: preparing a pressing member including a pressing portion, the pressing portion being located in the front of the pressing member in the moving direction; depressing the straight parts of the fiber bundle by the pressing portion toward the roots of the pins in the vicinity of the pins while moving the pressing member in the arrangement direction of the pins such that the pressing portion sequentially intersects the straight parts of the fiber bundle; and tilting the pressing portion such that, toward the end in the moving direction, the distance from the roots of the pins in the laminating direction of the fiber bundle layers increases.

motor 41, the threadedshaft 411, and thenut 42 configure a first adjustment part and a second adjustment part. - The first embodiment has the following advantages.
- (1) The straight parts Fy, Fb of the fiber bundle F engaged with the
pins 38 in the rows X1, X2 are depressed toward the roots of thepins 38 by thepress rollers press rollers pins 38, are small as compared to the conventional pressing member, which does not move while pressing. As a result, the size of thepressing device 39 is reduced. Thepress rollers - (2) The
press rollers pins 38 with which the fiber bundle F has been engaged. Thus, the fiber bundle F is pressed by thepress rollers press rollers - (3) Every time the fiber bundle layer is laminated, the pressing position of the
press rollers motor 41. Thus, the force that presses the fiber bundle F in the lateral direction (X-axis direction) does not become excessive when depressing the fiber bundle F by thepress rollers pins 38 are pressed by thepress rollers pins 38 are not bent. - (4) If the pressing position of the
press rollers press rollers press rollers press rollers pressing device 39 is reduced. - (5) Since two
press rollers - (6) If the pressing member that does not move during pressing like the
pressing bar 48 is used instead of thepress rollers linear sliders press rollers linear sliders - (7) The
press rollers guide pipe 31 are moved in the X-axis direction by the operation of thelinear sliders linear sliders guide pipe 31 in the X-axis direction, also function as a device for moving thepress rollers bundle arranging device 10 is simplified by using the first moving device also as the X-axis moving part. - (8) When pressing the fiber bundle by the press rollers instead of the
pressing bar 48, time required for forming the fiber bundle layer including the pressing operation is extended by the amount of time required for rolling the press rollers along the rows Y1, Y2 in the Y-axis direction. The configuration including thepressing bar 48 and thepress rollers pins 38 in two rows that are perpendicular to each other (rows X1, X2 and rows Y1, Y2) are pressed with only press rollers. - (9) In terms of the physical properties of the three-dimensional fiber structure, the fiber density of all the fiber bundle layers is preferably even. Every time the fiber bundle layer is laminated, the pressing position of the
pressing bar 48 and thepress rollers motor 41. Thus, the fiber density of all the fiber bundle layers is substantially even. Also, the structure in which the pressing position of thepressing bar 48 and thepress rollers motor 41 simplifies the structure of the fiberbundle arranging device 10. - The above-mentioned embodiment may be modified as follows.
- One of the press rollers (for example, the press roller 52) of the
pressing device 39 may be omitted, and thepressing device 39 may rotate about the Z axis by 180° from the state ofFig. 1 (a) . In this case, the remaining press roller (for example, the press roller 51) moves along the row X1 while rolling in the state ofFig. 1(a) , and when the entirepressing device 39 is rotated about the Z axis by 180° from the state ofFig. 1(a) , the remaining press roller (for example, the press roller 51) moves along the row X2 while rolling. - The two
press rollers - The
press rollers - The
pressing bar 48 may press the fiber bundle along the rows X1, X2, and thepress rollers - The fiber bundle may be pressed by the press rollers after one fiber bundle layer is formed.
- Instead of the press rollers, pressing
members Figs. 13, 14 may be used. The pressingmember 56 shown inFig. 13 includes a linearpressing portion 561, which is inclined such that, toward the end in the moving direction, the distance from the roots of the pins in the lamination direction of the fiber bundle layers increases. The pressingmember 57 shown inFig. 14 includes a curvedpressing portion 571, which is inclined such that, toward the end in the moving direction, the distance from the roots of the pins in the lamination direction of the fiber bundle layers increases. - The
press rollers - The pins do not need to be arranged linearly, but may be arranged to describe a curve. In this case, the press rollers preferably move along the curve of the arrangement of the pins.
- Instead of the
guide pipe 31, for example, a member including a fork attached to the distal end of a rod may be used, and the fiber bundle may be guided by the fork. - The pressing member may have any structure as long as the pressing member at least includes a pressing portion inclined such that, toward the end in the moving direction, the distance from the roots of the pins in the lamination direction of the fiber bundle layers increases, and may further include another inclined portion formed to face in the different direction. For example, a member like a reversed conical member may be used as the pressing member.
- The pressing portion does not need to be always inclined. For example, a pressing portion configured by a surface that is vertical at times other than when pressing is performed may be inclined only when pressing is performed.
